Abstract
The invention relates to an arrangement for eliminating radio interference in an electronic power regulator. The regulator comprises a switching unit (1) and a control unit (2), said switching unit (1) including two semiconductor switching units (5, 6) coupled in parallel, the first being a transistor switching unit (5) and the second a tyristor switching unit (6); said switching unit (1) is coupled in series with the load (3), and the power regulator regulates the AC current fed in the load, so that by means of the control unit (2), during the half-cycle of the supply voltage, at a point of time (t), the transistor switching unit (5) is first switched to conductive state, and immediately thereafter the tyristor switching unit (6) is also switched to conductive state, and both switching units (5, 6) are switched to cut-off state at the next zero point of the half-cycle. According to the invention, the arrangement comprises a coil (9) with a low inductance, or a corresponding inductor, which is arranged in series with the tyristor switching unit (6), so that the tyristor switching unit (6) and the coil (9) are in parallel with the transistor switching unit (5).
